Noise NavigatorTM Sound Level Database with Over 1700 Measurement Values E-A-R 88-34/HP Elliott H. Berger, Rick Neitzel1, and Cynthia A. Kladden 3M Personal Safety Division E•A•RCAL Laboratory 7911 Zionsville Road, Indianapolis, IN 46268-1650 317-692-3031 1 Univ. of Michigan, Dept. of Environmental Health Science, Ann Arbor, MI June 26, 2015; Version 1.8 Welcome to the Noise Navigator spreadsheet of sound levels for more than 1700 occupational, recreational, and military noise sources. The data are compiled from references in the literature and from our own measurements. For each source the reference is listed, and as available additional notes are provided. When the primary reference cites sources for its data, those too are listed. The tabled values are primarily A-weighted sound levels, as opposed to time-weighted average levels or Leqs. To determine exposures the user will have to factor in the total exposure time as well as the actual sound level that is present at the ear. For impulsive sounds, such as gunfire, the values are generally peak sound pressure levels (SPLs) and are so designated. A few of the sound levels are specified as "linear" indicating that they are unweighted; such levels will almost always be equal to or greater than A-weighted values, depending upon the amount of low-frequency energy that is present in the signal. The data are separated into groups by categories as shown on the Worksheet tabs. Additionally, for certain of the categories we have provided one or more additional worksheets with the data grouped by type, for example "lawnmowers," showing the average and the range of values for that source. The labels on the tabs are a brief indicator; see the top yellow row of each spreadsheet for an complete description of the source found on that sheet. The values are for representative sources at typical distances. When available, the distance at which the measurement was recorded is listed in the appropriate column. The actual sound levels for a situation are strongly influenced by the particular characteristics of the source in question, as well as the sound environment (reverberance) and the distance the user is from the source. Another critical factor, often unspecified in the references is the meter response of the instrument slow, fast, peak, or integrated values such as Leq or other. As an example of how such parameters can influence the results note that for typical popular music the difference between dBA slow and peak values is around 9 - 14 dB, and for broadband pink noise about 12 dB. The values in this spreadsheet can be sorted according to noise source, category of noise, and sound pressure level, or by any of the other columns, using the sort function in Excel. We are interested in refining and expanding this resource. If the reader has suggestions for improvement, or documented sound levels that they wish to share, or finds any items requiring explanation or correction, please contact Elliott Berger at Elliott.Berger@mmm.com.
